SPECIFICATION forming part of Letters PatentNo. 748,897, dated January 5, 1904.

To all whom it may concern.- J

Be it known that I, JAMES A. WALKLEY, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Hydrocarbon-Burner, of which the following is a specification.

This invention relates to means for atomizing liquid by a fluid, as air or steam under pressure.

An object of this invention is to provide superior means for atomizing crude petroleum and then vaporizing it` and afterward vintroducing it into the tire-box of the furnace in such a manner as to produce a most perfeet combustion and satisfactory distribu tio of the iiame.

yAnother object of this invention is to provide a serviceable atomizer the Wearing parts of which may be readily renewed in order to maintain a uniform outlet or discharge opening at minimum cost of'time and attention.

A further object is to provide au atomizer which is readily adjustable to increase or decrease the spread of name and also to vary the action of the expansive uid upon the issuing liquid.

Another obj ect is to provide means for preventing the admission of any scale or any object which might clog the steam-passage and fufacture and construction andease of assembling, taking apart, and reassembling thel device.

The accompanying drawings illustrate the invention.

Figure I is a broken lperspective view of an atomizer constructed in accordance with my invention. Fig. II is a plan of the member of the atomizer which is lowermost in Fig. I. The liquid-tube and its supporting-post and liquid -abutment are also shown in place. Fig. III is an elevation of thedischarge end of the atomizen Fig. IV is a vertical axial section on line IV VII, Figs. II and III. Fig. V is a fragmental sectional view on line VV, Figs. II and IV, showing intact the end of the oil-tube and a post which supports the same and forms an abutment at the front of the sides of the cylindrical post.

the duid-chamber for giving direction to the issuing fluid. Fig. VI is a fragmental sectional elevation on line indicated by VI VI, Fig. II. Fig. VII is a fragmental sectional elevation online IV VII, Fig. II, omitting the oil-tube and its post. Fig. VIII is afragmental section on line V VIII, Fig. II. Fig. IX is a plan of one of the Wearing-plates detached.

l 2 designate two sections of the atomizerbody, which may be solid blocks of metal fastened together by cap-screws 3 and may be identically the saine, with the exceptions which will be hereinafter noted. Their construction Will be readily understood by reference to the drawings. The sections are each provided With a dat joining face a to form together a steam-tight joint. In each face is a cavityh, which for convenience of manufacture is desirably circular."l Each face is also furnished at the outlet end with a iaring recess c, having grooves d at opposite corners in which Wearing-plates 4 4l may be respectively seated, one for each of said recesses. VThe Wearing-plates are slightly bowed and when slipped into place the spring of the plates frictionally retains them in position.

The plates are thus attached, -so as to be easily removable. The chamber b and the recess c are connected by the recess e, the walls of which are in arcs of a circle. A f designates seats for a post 5, which is desirablycylindrical and is seated concentricallywith the semicircular Walls g-of the passage at e, so that when the post 5 is in place there are 'curved passages, as at e, around Said post 5 is perforated transversely to receive the discharge end of a longitudinally-adjustable oiltube 6, which is desirably formed of a steel rod drilled from one end a part of `the Way toward the other to form Vthe tube and having a screw-threaded solid portion h at its rear end whichV is screwed into the screwthreaded seats il in the sectionsl l and 2 and desirably having a slot j to receive a screwdriver by which it may be turned for adjusting the oil-tube relative to the post 5 and the passages e.

One of the sections receives the oil and the other the expansive fluid.

rooH

la designates an oil-inlet formed in the section l, into which the oil-supply pipe m may be screwed, and n is a passage leading from the inlet 7c to a receptacle or chamber 0, formed in parts in the two sections and extending around the adjustable oil-tube 6, which is provided with intersecting bores p and q, the first of which extends across the oil-tu be to communicate with said chamber o, which is desirably circular for ease of construction, being formed by boring cavities into the two joining faces.

7 is the pipe for supplying an expansive fluid, such as air or steam, for atomizing the liquid suppliedthrough the pipe m.

r is a longitudinal passage in the section 2 into' which the pipe 7 may be screwed and which passage is provided with a screen 8, desirably cylindrical.

s is a passage leading from the passage r into the bottom of the cavity b in the member 2. The screen 8 is desirably cylindrical to Iit the passage r and to extend across the passage s for the purpose of intercepting any scale or other hard objects which might otherwise pass into the atomizer under the pressure of air or steam. j

. The screen 8 is removable and extends across the mouth of the passage s and may be readily Withdrawn endwise from the air or steam passage r for cleaning, though it l will seldom require cleaning, being free from liability to clog. By means of this screen I avoid the difficulty which has heretofore been experienced with atomizers having narrow slots through which steam or air is forced and in which scale from the boiler has heretofore from time to time been driven into the narrow slots, thus closing them and preventing the proper action of the burner. By

the construction shown the screen is perfectly 'supported against displacement or distortion by the steam-blast.

The discharge ends of the members l and 2 and the wearing-plates 4 and 41 are desirably formed in the segment of a circle in order to give a proper spread to ythe issuing mixture of expansive iuid and the atomized and vaporized liquid or fuel carried thereby.

When the post 5 is in place, the outlet from the chamberl b is desirably formed of four passages, two of which are each desirably composed of a curved portion converging forwardly in the arcs of a circle,and a straight portion r@which extends forward as an upright slot, and the two slots unite to form one slot, through which the outlet end v of the oil-tube 6 extends. The effect of the Walls of these two curved passages is to direct the expansive uid forward and crosswise over and under the end of the tube 6 and forwardly and sidewise away from the tube 6 at the points which lie in the hprizontal plane with the axis of the tube. The spreading action of the steam may be varied by moving the projectingend of the tube6 forward or backward, being increased when the tube is moved forward and decreased on the reverse movement.

w and :t are two other passages arranged, respectively, immediately above and below the tube 6 to direct two jets of the iiuid straight forward parallel with the extended axis of the tube 6Y to strike upon the inclined upper and lower faces of the walls of the outlet-recess c. By the arrangement set forth of the passages w, and t there are produced two pairs of diversely-directed streams of fluid. The oblique faces of the plates 4 and 41, which form said walls, direct toward each other the two jets, which issue through the passages t the upper jet downward and the under jet upward. The action of these several passages produce within the cavity formed by the recesses c a pressure of fluid subject to violent internal commotion producing a forcible breaking-up action on the oil', which thus becomes broken up and vaporized and will then issue from the outlet between the plates 4 and 41.

The purpose of forming the front end of the atomizer in the arc of acircle is to facilitate and direct the lateral spread of the flame.

By referring to Figs. IV,V, and VII it may be understood that the recesses ein the members l and 2, respectively, to form the curved passages around the post 5 terminate at their inner ends approximately in the same plane with the passagesw and or, so that the portion of the fluid which passes through. the passages at c will strike upon the slanting walls formed by the plates 4 and 4l, thereby being deflected and broken up to heighten the breaking and tearing effect of the expansive iiuid within the outlet-cavity.
